We had been going to Fleming's probably once a month for years, up until a couple of years ago. This place has changed radically since then. We knew going into this that it's not a cheap night - but the prices have gone up radically since we were last year, and the food quality has gone down. The portions were much smaller and about 50% more expensive. The service was fine and attentive, though.
With all the other upscale options in the Denver Tech Center, I would try them out before going to Fleming's.
